摘要：

This paper introduces a rectangular-frame aperture feed applied to a cylindrical dielectric resonator antenna (CDRA) to achieve circular polarization (CP). The CDRA has been placed on a square ground substrate to implement the antenna. A rectangular microstrip line is used to feed the aperture. The rectangular-frame aperture is oriented at a 45-degree angle relative to the microstrip line on the ground plane. This orientation generates the two orthogonal field components necessary for circular polarization within the CDRA. Based on the proposed theory, a right-hand circularly polarized (RHCP) antenna has been designed. The antenna structure was optimized and analyzed using high-frequency structure simulator (HFSS) software. The resulting design achieves an impedance bandwidth of 18.18% and a 3-dB axial ratio bandwidth of 15.75%. Additionally, the antenna demonstrates a gain exceeding 6 dB across the operating bandwidth. The effective bandwidth of this design covers the 3.5 GHz band, which is critical for the mid-band spectrum in 5G networks and other contemporary communication applications.
